Please bring this option back - Hue inversion was the reason I'd used this application extensively.

Yes, I think I'd seen that. That feature was very important to me, so now I don't have real use for this program (yet). I wonder why Apple did not...

Interesting, never thought about that direction. I think I encountered such an editor on the internet a few years ago; so it might be worth a search.

Perhaps one can attempt to edit their default/retina display profile at /Library/ColorSync/Profiles/Displays with the builtin property editor.

A filter which does inversion and hue inversion is easy to do, but it cannot be applied to a color profile I think.

I have managed to edit the standard Color LCD profile's tristimulus values with a hex editor. I think we need to understand how to rotate the projective coordinates values so...

I almost got it right. I altered the Color LCD profile as I described here https://dl.dropboxusercontent.com/u/6674137/ICC%20Modification.pdf. https://dl.dropboxusercontent.com/u/6674137/ICC-img.jpg

I edited the document. The colors' hue values are accurately inverted, but something is wrong with the grays. I suspect that the "Apple display native information > Phosphor values" section...

Here is the profile https://dl.dropboxusercontent.com/u/6674137/Invert%20Hue.icc. Hopefully someone can resolve the remaining little problem with lightness (I assume). Although the problem doesn't seem to be great, it does affect user experience;...

I think I forgot to invert the white point. Will do that tomorrow!
